 point A, B, C, D, E. Tell me what is A to B? A to B is constant velocity. So, shift to acceleration. Have you experienced this in class? Start accelerating. It's a very common thing, right? And then after observation we made in the last class was this. Let's solve a numerical based on this. 3 seconds. Tell me the displacement after 11 seconds. So, now everybody will guess the height, right? Right. Okay. When the velocity should increase an area shows should be subtracted from 34. 34 is the answer. It could be like this, like that. You may need to, you have two triangles, one and two and then probably this one could be the rectangle, right? So, like this. Last class and last to last class. Okay? So, just a quick revision. Now we can start solving some numericals. Okay? Okay, the chemistry in math will be a little bit more thicker. Yeah, bio. Okay, guys pay attention. Right now. Okay? So, we have to write in terms of, in terms of what is given to us. 0 to 5 seconds, 5 to 7, 7 to 9. What is the velocity between these? I mean, what is the velocity for these 3? 0 velocity. 5 to 7 it is? 0. Displacement is 0 and 8. So, this is 4 by itself. Minus g and displacement, so minus h. Now I have to. So, we will be using minus h, u is 0, equation is minus g. So, from here you can see that the velocity is equal to under root of 2h 5g. Fourth second. In fourth second, how much distance it has travelled? Four seconds how much it has travelled? I am asking you, on that fourth second, four meters. In the third second, I will be travelling four meters. In the fourth second, I may be travelling six meters in four distance. Can I get? As you tell me one second. Quickly. Don't do it verbally. I know it is a tense, straight forward. Tense. It will be travelling three, I have taken four. So, it is 12 or 16, 28 meters. It has travelled. Can I use this one normally? In three seconds how much it has travelled? How much it has to travel? 21. 21. 21. 21. 80. Yes, 80. Yes, 80. Don't be casual, you know. You have to write it down and solve it. 3 into 3 square. So 9 plus 9, 18 meters. Now, can you tell me how much distance it has traveled in the fourth second? 21. This, my understanding? Getting it? So like this, you can get particular distance traveled in the nth time. Getting it? Yes. And then you subtract it. That is the time. That is the distance traveled by the opposite. So there was a balloon. Do you feel in control or do you remember this much? It's from here. Okay? 2 seconds. See, all of them are going below. You have to find the velocity of that of its dropping. It is not dropping. After 2 seconds of it dropping, whatever is velocity. One thing is taken for that, you start feeling in control. Okay, fine, I know something. Of course, ordering. All right, delicious. Here. Keep on reminding. This is your card. Okay? The movie made at extremely high speed. Okay, you drop it. You have thrown. Okay. And then drop it. The ball will move. The ball will drop. Okay. And then you throw the ball up. And then when you come to the front, the ball is going to land or move to the front. You will be carrying the ball. Because it will drop to the front. Correct. A simple example which is more day-to-day life. Keep quiet. When the ball is not on the smartphone, right? Okay, when the ball... So that we can so that he can throw the ball with whatever strength he has. Plus, what he will be carrying with his feet. So that is what the ball is. Okay. Now solve it. Now what is the answer? Minus 7. Minus 7. Now is it 10 or 12? 12. 12. 12. So you is 2 Minus 9.8 into 2. Yes or no? 2 minus 2 minus 19.6 which is minus of 17.6 meter per second. Fine. If I ask you... 17.7 Spirit cannot be negative. Because it does not have 9. Any doubts? Just a few seconds. That's what you are taking time. Yes. After 2 seconds, what is happening? That is what we have found. Any doubts? This guy doesn't want to play. So...
